SEED-PLANTER.

SPECIFICATION forming part of Letters Patent No. 698,004, dated April22, 1902.

Application filed July l24, 1901.

To @ZZ whom, t may concern:

Beit known that I, TIMOTHY J. GAYNOR, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,haveinvented a new and useful Seed-Planter, of which the following is aspecification.

My invention relates to an improvement in means for operating thedropping mechanism of a seed planter or drill.

The object of my invention is to produce a seed-planter capable ofdropping the seed at regular predetermined distances without the use ofa check-wire and of such character that inequalities in the movement ofthe lnachine in different rows may be easily and quickly compensated.

The accompanying drawings illustrate my invention.

Figure 1 is a plan of a machine embodying my invention. Fig. 2 is avertical section on line 2 2 of Fig. 1.

In the drawings, 5 indicate ,parallel arms ofa main frame, in which isjournaled the axle 6, carried by supporting-wheels 7 7, one of which issecured to the axle 6, so as to rotate the same.

Mounted upon the main frame or connected thereto in any desired mannerare the seedboxes 8 8, each of which is provided with any desired formof dropping mechanism (not shown) operating by a rock-shaft 9, normallyheld at one extreme of its oscillation by a spring 10 in the mannerusual in check-row planters. Revolubly mounted upon shaft 9 is asprocket-wheel 11, and secured to shaft 9, one upon each side of thesprocket 11, are two arms or lingers 12, the purpose of which willappear.

Mounted upon each of arms 5 and longitudinally adjustable thereon by anysuitable means, such as set-screws 13, is a box 111. Journaled in thetwo boxes is a counter-shaft 15, to which is secured a sprocket-wheel16and a bevel-pinion 17. Rotatably mounted upon counter-shaft 15 is asprocket-wheel 18, provided with a clutch member 19. Coperating withclutch member 19 is a clutch-collar 20, splined upon shaft 15 andnormally held .serial No. 69,467. (No model.)

in engagement with the ,part 19 by means of a spring 21. Collar 2O isengaged bya lever 22, which in turn is engaged by a cam 23, carried by afoot-lever 24. Secured to the axle or shaft Gis a sprocket-wheel 25, andpassing over said sprocket-wheel and the sprocket- Wl1eel18is a chain26. Passing oversprocketwheels 16 and 11 is a check-chain 27, providedat intervals with links having oppositely-extending ears 28, which areadapted to be brought into engagement with the fingers 12 of the shaft9, being held in engagement With 'said fingers through a certainrequired distance by means of a guide 29. Meshing with the bevel-pinion17 is a pinion 30, secured to the lower end of a shaft 31, provided withan operating-Wheel 32, which is brought up toward the seat in positionwhere it may be readily grasped bythe operator.

Chain 27 is preferably of the separable-link type in order that anydesired number of links carrying the ears 28 may be placed in the belt,by means of which the distance traversed by the machine between dropsmay be accurately controlled. The adjustability of the counter-shafttoward and from the rockshaft materially aids in desired arrangements ofthe ear-carrying links of the belt 27.

In operation the forward movement of the vehiclecauses a rotation ofshaft 6 in the direction indicated by the arrowand through sprocket 25,chain 26, and sprocket 18 rotates counter-shaft 15 in the samedirection, the rotation of said shaft through clutch-collar 2O causing arotation of sprocket 16 and a movement of belt 27, so as tointermittently bring the ears 28 into engagement with the fingers 12,soas to intermittently operate the dropping mechanism. If for any reasonthe drop takes place too soon, the operator by moving footlever 241 maythrow clutch-collar 2O out of engagement with the sprocket 18, and thusretard chain 27, so as to delay the operation of the next drop. If, onthe other hand, the drop is too late, the operator by grasping Wheel 32may advance shaft 15, and consequently advance chain 27 ahead of orfaster than the movement which would be imparted by the shaft 6. Bymeans of the wheel 32 the belt 27 may be advanced and the droppingmechanism operated while the machine is standing.

I claim as my invention- 1. In a seed-planter, the combination with adropping mechanism, of a belt provided with means for intermittentlyoperating said dropping mechanism, a wheel rolling uponv theground,driving means between said wheel and belt, means fordisconnecting said belt from the driving-Wheel, and means for advancingsaid belt independent of its driving- Wheel Without disconnecting saidbelt from the driving-Wheel.

2. In a seed-planter, the combination with the main frame,supporting-wheels, and the axle thereof, of a counter-shaft, separabledriving connections between said countershaft and axle, means forseparating said connections, a rock-shaft forming part of a droppingmechanism, a belt driven by the counter-shaft, means carried by saidbelt for intermittently engaging and operating the rock-shaft,and meansfor rotating the countershaft independent of the axle withoutdisconnecting the counter-shaft from the axle.

3. In a seed-planter, the combination with the main frame,supporting-Wheels and the axle thereof, of a counter-shaft, separabledriving connections between said countershaft and axle, means forseparating said connections, a rock-shaft forming part of a droppingmechanism, means for adjusting the counter-shaft toward and from therock-shaf t, a belt driven by the counter-shaft, means carried by saidbelt for intermittently engaging and operating the rock-shaft, and meansfor rotating the ccunter-shaft independent of the axle.

4. In a seed-planter, the combination with a main frame,supporting-wheels, and axle, of a counter-shaft, a wheel rotatable uponsaid counter-shaft and carrying a clutch member, a belt passing oversaid Wheel and the axle, a clutch member splined upon the counter-shaftand normally held in engagement with the other clutch member, a beltdriven by said counter-shaft, dropping mechanism, means carried by saidbelt for intermittently operating the dropping mechanism, a handshaft,and a driving connection between said hand-shaft and counter-shaft,substantially as and for the purpose set forth.

5. In aseed-planter, the combination with a dropping mechanism, of awheel rolling on the ground, driving connections between said wheel anddropping mechanism, means for disconnecting said connections between thewheel and dropping mechanism, and means for advancing said connectionsindependent of the wheel but Without disconnecting the drivingconnections.
